"Face Mask"

[Grek]

Its not a question of it being realistic. It's a question of, "What does this add to the game other than being really gross?" This idea doesn't add new crime options, since it would be much easier to just steal their ID and wear a gas mask. More effective, too, if face masks rot. There's no non-crime reason to cut someone's face off and wear it as a mask, other than aesthetics. But if its aesthetic only, why have it rot off? Having the masks rot isn't required for traitor balancing, since steal face + voice changer is not some sort of OP combo. Its not in line with other mechanics, since we don't have worn butts decay on top of people's heads. Basically, what I want to know is:

1. What does being able to cut someone's face off and wear it add to the game that gas mask + ID doesn't?
2. Why does access to these masks need to be made limited time only and/or unreliable by big red rotting face messages?
3. Why go with the ultra gross 'decaying severed faces' option instead of some kind of temporary latex costuming?
